This quantity is given in terms of the s and p character of orbitals by Coulson's theorem, and it is predicted to be larger for singlet carbenes than triplets. An attempt to reconcile the optimal value of this quantity with that which is demanded by small cyclic hydrocarbons results in banana bonds. This quantity is dramatically smaller than predicted for hydrogen (*) disulfide because of lone pair donation into sigma star orbitals.

This quantity is given in terms of the s and p character of orbitals by Coulson's theorem, and it is predicted to be larger for singlet carbenes than triplets. An attempt to reconcile the optimal value of this quantity with that which is demanded by small cyclic hydrocarbons results in banana bonds. This quantity is dramatically smaller than predicted for hydrogen (*) disulfide because of lone pair donation into sigma star orbitals. This quantity is decreased in VSEPR theory when one replaces a substituent with an electron pair, because the electron pair is more repulsive and compresses the other substituents. For 10 points, give this measure, equal to approximately 109.5 degrees for methane and 104.5 degrees for water.
